Gever Tulley, founder of the Tinkering School, talks about our new wave of overprotected kids -- and spells out 5 (and really, he's got 6) dangerous things you should let your kids do. Allowing kids the freedom to explore, he says, will make them stronger and smarter and actually safer.

Here they are:

1. Play with fire.
2. Own a pocket knife.
3. Throw a spear.
4. Deconstruct appliances.
5. Break the DMCA.
Bonus. Drive a car.

This is from TED University, so it's not quite as flashy or polished as the talks from the TED Conference, but it makes the point.
